An apple has no fat, few calories, lots of soluble fiber, and antioxidants. What does a potato chip offer? Pretty nil on the valuable nutrients score, and it's a great source of oil, calories, and salt. A good rule of thumb is to go with foods that come packaged by Mother Nature, i.e., apple (skin) versus chips (plastic bag), banana (peel) versus candy bar (wrapper). Both you and the environment will be around longer to enjoy each other.
